I have several Internet "personas" because I volunteer for several organizations and have my personal social media, webmail, etc.
So I keep different profiles in Firefox and Chrome to meet those needs.
If Opera had profiles like that, it'd be my goto browser in heartbeat. I think Speed Dial is the greatest thing to hit web browsers since multiple tabs.
Anyone know why Opera doesn't implement profiles? With so many people sharing computers it seems like pretty baseline functionality these days.
